Definition of subrogation in English:

noun

The insurer could not sue them in the owner's name (exercising rights of subrogation under the insurance policy) because they were all entitled to indemnity under the same policy.

The point is now practically unimportant since the fears raised were soon obviated by an informal agreement among insurance companies not to enforce their rights of subrogation in this respect in the absence of fraud.

Nothing can affect his rights and there is no question of competition between him and the party claiming subrogation.
